Quebec building code question

What are the Quebec building code requirements for fire safety?

Fire safety requirements in Quebec are governed by the Code de construction du Québec, which adopts NBC fire safety provisions with Quebec-specific amendments. The RBQ administers enforcement, and Quebec may also reference the Code de sécurité for existing buildings.

Fire safety in Quebec buildings involves the Code de construction du Québec for new construction and major renovations, and potentially the Code de sécurité (Safety Code) for existing building maintenance. The construction code adopts NBC fire safety provisions with amendments, while the safety code addresses ongoing fire safety obligations for building owners. Understanding which code applies — and where Quebec amendments change the NBC baseline — is critical for compliance.

What to check first

  • The Code de construction du Québec adopts NBC fire safety provisions with province-specific amendments.
  • Quebec also has a Code de sécurité that governs ongoing fire safety obligations for existing buildings.
  • The RBQ administers enforcement of both the construction code and the safety code.

Jurisdiction notes

Construction code vs safety code

Quebec distinguishes between the Code de construction (for new work) and the Code de sécurité (for existing building safety). Both may apply depending on the project.

Quebec amendments to NBC fire safety

Quebec amendments can modify fire separation ratings, sprinkler requirements, fire alarm provisions, and other fire safety elements compared to the NBC baseline.

RBQ enforcement

The RBQ enforces both codes and may have specific interpretation bulletins or guidance documents that affect fire safety compliance.

Work through it in this order

  1. Determine whether the project involves new construction, renovation, or existing building maintenance to identify the applicable code.
  2. Review the Code de construction du Québec fire safety provisions and identify any Quebec amendments to the NBC baseline.
  3. Check whether the Code de sécurité imposes additional requirements for the existing building condition.
  4. Document the specific code clauses, amendments, and any RBQ guidance that governs the fire safety design.
